Commercial properties in the Netherlands are primarily governed by the Besluit bouwwerken leefomgeving (Bbl), the Dutch Building Decree that sets minimum fire safety requirements for construction, renovation, and change of use. European standards, in particular the EN 13501-2 series, define how fire resistance is classified and tested. Depending on the sector and the nature of the activity, additional regulations from bodies such as PGS15 or an environmental permit may impose stricter requirements on top of the Bbl baseline. The sections below unpack each layer of that regulatory framework and explain what it means for a specification.
What laws govern fire safety in commercial buildings?
Fire safety in commercial buildings in the Netherlands is governed by the Besluit bouwwerken leefomgeving (Bbl) as the primary national building code, supported by European harmonised standards under the Construction Products Regulation (CPR). The Bbl defines minimum performance requirements for fire compartmentation, escape routes, and structural fire resistance. European standards such as EN 1634-1 define how products are tested, and EN 13501-2 defines how results are classified.
The CPR requires that any fire-rated door placed on the European market carries a CE marking, meaning it has been tested by an accredited body and classified according to EN 13501-2, the European standard for fire resistance of building elements. This is the classification system that produces the EW and EI designations architects see in product documentation. For industrial fire doors, two CE-relevant standards apply simultaneously: EN 16034 (fire- and/or smoke-resisting closing elements) and EN 13241 (industrial doors generally). These are not interchangeable — both apply at the same time.
At the national level, the Bbl replaced the older Bouwbesluit 2012 and integrates fire safety requirements within the broader framework of the Omgevingswet. For architects specifying products for Dutch projects, the Bbl is the starting point — but it sets only the absolute minimum. For projects outside the Netherlands, equivalent national transpositions of the same European directives apply, though some countries add additional national requirements on top of the CE baseline.
Metacon-Next manufactures fire-rated industrial doors that are CE-certified and independently tested by Efectis, ensuring full compliance with EN 1634-1 and the classification requirements of EN 13501-2. You can explore the full product range at Metacon-Next’s product overview.
What fire resistance classification does a commercial property need?
There is no single universal fire resistance classification that applies to all commercial properties. The required classification depends on a project-specific fire safety calculation that accounts for building use, floor area, occupancy, evacuation strategy, and fire compartment size. The Bbl sets only a minimum baseline; the actual requirement for a given opening is determined by the fire safety engineer assigned to the project.
Understanding EW and EI classifications
Fire resistance classifications for doors follow the format defined in EN 13501-2. The three most relevant criteria for commercial and industrial applications are:
- E — integrity: the door prevents flames and hot gases from passing through for the stated duration.
- EW — the door maintains integrity (E) and limits radiant heat transfer (W) for the stated duration. W is the Dutch standard baseline criterion and is the typical default classification in many standard Dutch commercial and industrial applications.
- EI1 and EI2 — the door maintains integrity (E) and provides thermal insulation (I) for the stated duration. EI1 is the stricter criterion, limiting temperature rise on the unexposed side to a lower threshold. EI2 is the less strict criterion, permitting a higher temperature rise on the unexposed side. Always specify EI1 or EI2 explicitly — never write “EI” alone without the suffix.
EW and EI1/EI2 are not interchangeable. Specifying EW where EI2 or EI1 is required by the fire safety calculation is a compliance failure. Always confirm the required classification with the project’s fire safety engineer before writing it into a specification.
Common duration classes in industrial applications
Duration is expressed in minutes appended to the classification: EI2-60, EW 90, EI1-120, and so on. In logistics centres and production halls, EW 60 is the Dutch standard baseline and EI2-60 is a common alternative, but neither is a universal rule. Large fire compartments, hazardous materials storage, or buildings with complex evacuation routes may require longer durations or a heavier classification. The fire safety calculation — not the building type alone — determines the required classification and duration. For any specific project, consult a qualified fire safety engineer or contact Metacon-Next directly.
How does the Dutch Building Decree (Bbl) set fire safety requirements?
The Bbl sets fire safety requirements through a performance-based framework: it specifies outcomes — such as limiting fire spread between compartments — rather than prescribing a single product solution. For fire compartmentation, the Bbl defines maximum compartment sizes and minimum fire resistance durations for separating constructions, but these are absolute minimums. A heavier classification than the Bbl baseline may be required for several reasons: the project deviates from standard building regulations, a sector-specific regulation such as PGS15 applies, the client sets a stricter above-statutory requirement, or an insurer imposes a stricter requirement. The Bbl itself does not change the classification requirement — what changes is the situation that makes a heavier classification necessary.
The Bbl distinguishes between new construction, renovation, and change of use. New construction is held to the most stringent requirements. Renovation projects are assessed against the standard for existing buildings, which is generally lower but still binding. A change of building use — for example, converting a warehouse into a data centre — triggers a reassessment and may require the new use class requirements to be met in full.
For architects, the practical implication is that the Bbl provides the floor, not the ceiling. A specification that meets only the Bbl minimum may still be rejected during a fire safety review if the project’s fire safety plan calls for a higher performance level. Always cross-reference the Bbl requirements against the project’s fire safety documentation before finalising the specification.

Which fire safety documentation must a commercial building specification include?
A complete specification for a fire-rated door in a commercial building must include the CE declaration of performance, the classification report from an accredited test body, and the relevant technical data sheet. For projects targeting sustainability ratings such as BREEAM or LEED, an Environmental Product Declaration (EPD) is increasingly required as well. Incomplete documentation is one of the most common causes of delays during permitting and fire safety reviews.
The CE declaration of performance confirms that the product has been assessed against the relevant harmonised standards — for industrial fire doors, both EN 16034 and EN 13241 apply simultaneously — and meets the declared performance. The classification report, issued by the accredited test body (Efectis, in Metacon-Next’s case), provides the technical evidence behind the CE marking. Together, these two documents are the minimum an architect needs to justify a product choice to a building inspector or fire safety reviewer.
EPDs have moved from optional to expected in many project types. An EPD is an information document, not a sustainability award: it transparently reports the environmental impact of a product across its lifecycle based on ISO 14044 and EN 15804. It does not certify that a product is sustainable, but it provides the data a BREEAM assessor or a client with ESG commitments needs to score the project correctly.
Metacon-Next publishes classification reports, CE declarations, and EPDs openly for its product lines. All EPDs were published in 2025 and cover eleven main product lines. Architects can access this documentation without needing to request it separately, which eliminates a common source of specification delay. You can request a quotation and receive accompanying technical documentation as part of the process.
When do sector regulations override standard building code requirements?
Sector regulations override or supplement the Bbl when a specific activity or stored substance introduces risks that the general building code does not adequately address. The most prominent example in Dutch industrial practice is PGS15, the publication series governing the storage of hazardous substances. PGS15 imposes fire resistance requirements on storage compartments that are often stricter than the Bbl baseline, and compliance with PGS15 is typically a condition of the environmental permit rather than the building permit.
Other sectors where additional requirements are common include:
- Healthcare: Facilities accommodating non-ambulatory occupants are subject to stricter compartmentation and evacuation requirements, often specified in sector-specific guidelines that go beyond the Bbl.
- Cold storage and logistics: Large warehouse facilities may face insurer-driven requirements for fire compartment sizes and door classifications that exceed the statutory minimum. The applicable classification — whether EW, EI2, or EI1, and for what duration — depends on the project-specific fire safety calculation, not on the building type alone.
- Data centres and server rooms: Environmental control requirements and the value of the contents frequently lead clients or insurers to specify fire resistance durations well above the Bbl floor.
- Explosive atmospheres (ATEX zones): Facilities handling flammable gases or dusts require doors that meet both fire resistance and explosion-pressure criteria simultaneously.
The practical consequence for architects is that the applicable regulatory framework for a project must be established early, before the specification is drafted. A door that satisfies the Bbl may not satisfy PGS15, and a door that satisfies PGS15 may not satisfy an insurer’s additional requirements. Identifying all applicable frameworks at the outset prevents costly specification revisions later in the project. For any situation where multiple frameworks may apply, consult a qualified fire safety engineer or the local authority — the correct classification for a specific project cannot be determined from building type or general guidance alone.
